Butech colorstuk rapid grout question

[On one]

Is the aforementioned grout suitable for grouting porcelain tiles on it's own over electric UFH or do you have to mix in an additive? plenty of bumf on the back of the bag but no mention of flexibility or porcelain tiles.(customer supplied materials is the reason for my uncertainty)

I just grouted roughly 220m2 with it over ufh so I hope it is..
As far as I know it is fine.
How long did it take you to find the English on the back of the bag?

Its flexible, know whay you mean by the writing, its a nightmare!

I'm just worried that in all that text on the bag......not one mention of the word flexible!

It's fine.
Surprisingly "similar" to Mapei UCP isn't it?!

I'm using it for the first time tomorrow...thats the reason for the panic!

Just used it yesterday to grout 6m of mosaics over UFH, goes off pretty quick so beware. Lovely to work with and dries very even colour, no light or dark patches and that was with anthracite.

I used the Butech colorstuk rapid today and I thought it was better than the UCP,but it is made by Mapei though!
